Chromium is a browser similar to Google Chrome and uses the same code base. Chromium omits some components including Google's brand, auto-update mechanism, RLZ identifier, as well as the bundled Adobe Flash Player and PDF viewer.

Chromium Portable is a custom-built version of the dev channel of the Chromium web browser. It is packaged in the PortableApps.com Format and supports jPortable.

NOTE: this project is dormant with no release since July 2017 and as such may be subject to security issues. Proceed with caution.

I started to notice problems in Chromium 42 with Flash and found out that Chromium is deprecating NPAPI plugin support. This means that Flash (and other NPAPI plugins) will not work properly unless you use the PPAPI versions. For Flash, you can use PepperFlash.

@fredazoid ~ I just happen to have a machine with a 3.5 floppy still in use. Yes, the latest Chromium portable lights up on mine as well. Just for comparison, I tried the latest Iron portable - no reaction from the floppy.
